以7个切花红掌(Anthurium andraeanum)品种为供试材料,研究了低温胁迫对其离体佛焰苞与叶片形态以及叶片的质膜相对透性、渗透调节物质含量、抗氧化酶活性等指标的影响。在此基础上,运用逻辑函数方程计算半致死温度(LT_(50)),运用隶属函数法计算隶属函数值,并根据两者结果分析各品种耐低温的能力。结果表明,经6°C低温处理48 h后,切花红掌品种‘火焰’、‘热情’和‘米多蕊’冷害症状最轻,‘干杯’和‘玛丽西亚’冷害表现居中,‘趣味’和‘天使’的冷害表现最重;随着低温处理时间的延长,各切花红掌品种的相对电导率(REC)以及丙二醛(MDA)和渗透调节物质含量逐渐上升;抗氧化酶活性呈先上升后下降的趋势,且增幅与到达峰值时间点不同。各品种的LT_(50)在-7.19～-5.21°C之间,各指标隶属函数在0.017～0.981之间。根据各指标的相关性分析,REC、MDA含量、可溶性蛋白含量、超氧化物歧化酶(SOD)活性和过氧化物酶(POD)活性5个生理生化指标可作为切花红掌耐低温能力的评价指标。通过综合评价和聚类分析法对各品种进行耐低温排序,将其分为3个等级:‘火焰’、‘热情’和‘米多蕊’耐低温能力最强,‘干杯’和‘玛丽西亚’次之,‘趣味’和‘天使’耐低温能力最弱,这与佛焰苞和叶片的冷害表现结果一致。

Protein nanocages are ideal templates for the bio-inspired fabrication of nanomaterials due to several advantageous properties. During the mineralization of nanoparticles （NPs） inside protein nanocages, most studies have employed a common strategy： seed formation inside protein nanocages followed by seeded NP growth. However, the seed formation step is restricted to gentle reaction conditions to avoid damage to the protein nanocages, which may greatly limit the spectrum of seed materials used for NP growth. We put forward a simple route to circumvent such a limitation： encapsulation of a preformed NP as the seed via self-assembly, followed by the growth of an outer metal layer. Using such a method, we succeeded in mineralizing size-tunable Au NPs and Au@Ag core-shell NPs （〈10 nm in diameter） with narrow size distributions inside the virus-based NPs of simian virus 40. The present route enables the utilization of NPs synthesized under any conditions as the starting seeds for nanomaterial growth inside protein nanocages. Therefore, it potentially leads to novel bioinorganic chimeric nanomaterials with tailorable components and structures.

The syntheses of three novel substituted indanones namely 2,7 dimethylindan 1 one, 2 methyl 4,7 diethylindan 1 one and 2,4 dimethyl 7 methoxyindan 1 one are described. These indanones were prepared by different routes involving intramolecular ring closure of aryl substituted compounds by Friedel Crafts reaction. The t butyl was used as the positional protective group in the selective preparation of 2,7 dimethylindan 1 one. The corresponding indenes were prepared by reduction and dehydration reactions from these indanones.
